Oakland Raiders quarterback Carson Palmer is unlikely to restructure his contract, according to ESPN.com.

Palmer is set to make $13 million in base salary for the 2013 season. If he doesn't restructure his deal, the Raiders are faced with a decision: Keep the 33-year-old signal caller at his current salary or release him and look elsewhere for a starter.

The Raiders acquired Palmer during the 2011 season in a trade with the Cincinnati Bengals for a 2012 first-round pick and a 2013 second-round pick.

Raiders general manager Reggie McKenzie has previously said that backup quarterback and former Ohio State star Terrelle Pryor would get a chance to compete for the starting job. Pryor has attempted 30 passes in two NFL seasons.
